IMPROVEMENT IN CAR-COUPLINGS.

Specification forming part of Letters Patent No. 108,404, dated October18, 1870.

To all 'whom it lmay concern:

Beit known that I, WARREN B. SNEDAKER, of Phoenix, in the county ofOswego and State ot' New York, have invented a new and ImprovedCar-Coupling; and I do hereby declare that the following is a full,clear, and exact description thereof, which will enable others skilledin the art to make and use the same, reference being had to theaccompanying drawing, forming part of this specification, in which-Figure l represents a side view, partly in section, of my improvedcar-coupling. Fig. 2 is a plan or top view, partly in section, of thesame. Fig. 3 is an end view of the same. Fig. 4is a plan view of thelink. Fig. 5 is a longitudinal section of the link.

Similar letters of reference indicate corresponding parts.

This invention is an improvement in the class of car-couplingswhichisknown as selfcoupling;77 and the improvement consists in thepeculiar construction and arrangement of the devices constituting thecoupling, whereby they are adapted to operate as hereinafter set forth.

A A in the drawing represent the drawheads of two cars. B is thecoupling-link. This link has an additional amount of metal, a, at oneend, so that it is heavier and will be held horizontal by the additionalWeight.

In ears b b, that project from each drawhead, is hung a transverseshaft, E, which has projecting cranks c o, to the ends of which the pinD is pivoted. The pin D ts through a slot of the draw-head, and issupported on the cranks c by means of a projecting flange, d. It is alsoprovided with a projecting knob, e, to facilitate handling.

The shaft E has, furthermore, two project ing arms, f f, which areweighted at the ends to hold the pins down. When, by raising the knob e,or swinging the shaft E, the pin D is raised, it is drawnlforward, andwill thus clear the link without requiring the cars to be pushedtogether. When the car is uncoupled the pin will hang the same as whencoupled, but will yield to the inserted link to permit automaticcoupling, the weighted arms drawing it down again immediately after itis clear at the lower end.

The ears b have stops g, which arrest the cranks c, preventing theraising of the pin beyond the necessary height.

Having thus described my invention, I claim as new and desire to secureby Letters Pat ent- The coupling-pin D, provided with the lange d, theshaft E, crank-arms c, and weighted arms ff, combined with the slotteddraw-head A, provided with stops g, all constructed and arranged in themanner shown and described.
